PATENT OFFICE To sEGAL AUTOMATIC Twnnzian conil CORPORATION or NEW YORK LIGHTER Application flied September 27, 1927. Serial No. 222,280.

This invention relates to an improved lighter of that type which is commonly carried in the pocket, and is primarily used as a smoke'rs appliance or accessory.

' It is an object of the invention to provide a device of this character, in which the parts will be relatively few in number and individually simple and rugged in construction, and in which these parts may be assembled with facility to provide a lighter capable of being sold at a relatively low figure, and which will give service over a long period of time with freedom from mechanical difiiculty.

A further object of the invention is that of providing a device of this character in which the several parts will normally be held in properly assembled condition but in which, when it becomes necessary to disassemble the mechanism of the lighter, this may be achieved readily.

A further object is that of constructing a lighter in which the parts may be retained against loss and in which, when it becomes necessary to replace certain of the parts incident to their wearing, this may be accomplished with facility.

With these and further objects in mind, reference is had to the attached drawings, showing one practical embodiment invention and in which:

Figure 1 is a side elevation of the lighter with certain of the parts broken away to disclose the underlying construction.

Fig. 2 is a plan view thereof.

Figs. 3 and 4 are enlarged sectional views taken along the lines 33 and 4-4 and in the direction of the arrows shown respectively in Figs. 2 and 1, and

Fig. 5 is a perspective view of the fiintor spark-producing wheel.

In these views the numeral 10 indicates the of the present casing of the lighter, which may be formed of any suitable material and which, in common with prior lighters, may have its interior filled with a mass of fibrous substance 11, the latter being impregnated with a suitable volatile and readily ignitable fluid such as, for example, gasolene, which may be introduced into the casing through the base opening thereof, which is normally closed by the plug 12.

Extending from the upper face or deck of the casing 10 is a wick nozzle or spout 13 through which a wick 14 of any desired type may extend. A post 15 also extends from this upper surface as do also a screw-threaded stem 16 and a lug 17, it being here noted that the lug and stem are disposed preferably on one side of the upper face of the casing and in line with each other, the wick nozzle 13 and post 15 being likewise disposed in line with each other and preferably upon the opposite side of the casing top.

As shown in Figure 4, the post 15 is formed with a bore 18 from which a slot 19 extends towards the line of the lug 17 and stem 16, the upper edge of the post being bifurcated. Mounted between the arms thus provided and by means of a pivot pin 20 is the lever 21 of a wick snufier or cap 22, which latter is arranged when the lever is in substantially horizontal osition to cover the upper end of the wick tu e or nozzle 13. In order to hold this element normally in the position stated, as well as with. a'view to maintain the cap in elevated position when the latter is raised, the inner end-of the lever 21 is squared, as at 23, and extends materially beyond, the pivot 20. Held within the bore 18 is a spring-pressed pin 24 which has a foot portion 25 for contact with either of the flat surfaces 23, it being noted that the corners between adjacent surfaces are preferably rounded. As a consequence, while by means of this construction the lever and cap attached thereto will be retained automatically in either substantially horizontal or vertical positions, shifting from one to the other position may be effected readily, this movement resulting in an initial depression of the pin 24 and a subsequent projection thereof.

The upper end of the stem 16 is formed with a transverse opening of a size suflicient to accommodate a barrel 26 and a collar 27 encircles the stem and is mounted upon the screw threads so that, as in Figures 1 and 3, it may be raised to contact with the'under surface of the barrel 26. At this time it will be observed that the latter element prefertoo ably has its under face flattened as at 28, so that a maximum clamping action may be exerted by the collar to prevent play between the barrel and the stem.

Mounted within the bore of the barrel is a spring 29, one end of which acts against a flint 30, preferably through the medium of an interposed headed pin 31. The end of the barrel preferably terminates in a forked portion 32 between the arms of which a flintor spark-producing disk 33 is mounted. This mounting is conveniently accomplished by a shaft which, according to the present invention, has its upper end reduced, as at 34 and bears in the upper arm of the fork 32, its body being enlarged as at 35 and passing through and bearing against the sides of the opening in the lower arm of the forked portion. The body 35 is formed with a flattened and shouldered part 36 and the flintor spark-producing disk 33 is correspondingly recessed so that relative rotation of these elements is precluded, it being understood that axial movement thereof is limited by virtue of the confined space afforded between the arms of the forked portion. The lower end of the shaft 35 terminates in a thumb wheel 37 which preferably forms an integral part of the shaft, the lower face of this wheel having rotatable bearing with the upper face of the deck of the casing 10, or being otherwise suitably supported to rotate freely, and it being here noted that the plane of contact between the flint 30 and disk 33 is substantially in line with the wick nozzle 13.

With a view to maintaining the spring 29 under sufficient tension to effect proper contact between the flint and disk, a set screw 38 has its inner end extending into the bore of the barrel 26 and bearing against the spring 29. This screw is mounted by pivotally securing a link 39 to the lug 17 and forming this link with a screw-threaded opening for engagement with the threads of the screw 38, this opening being axially aligned with the barrel bore. To prevent an accidental detachment of the set screw from the link the end threads of the former are preferably mutilated. Thus, while the screw may be projected or retracted it may not be detached from the link and when retracted it is obvious that this link may be swung around its pivot to afford free access to the interior of the barrel.

Preferably the member 38 has the convolutions of its screw threads interrupted by flat surfaces 40, and at this time it will be noted that the pin 24 carries an arm 41 extending outwardly through the slot 19 for engagement with these flattened surfaces. Consequently, while, when the lever 21 is swung upwardly the arm 41 will be out of contact with the set screw 38 and the latter may be freely shifted, it will be understood that in normal position a rotation of the set screw is prevented by the engagement therewith of the arm 41.

Thus a lighter is provided by means of which, among others, the objects specifically aforementioned are achieved, it being noted that the disk 33 will remain firmly fixed with respect to the shaft upon which it is mounted. But when it becomes necessary for any reason to remove the disk, this may be accomplished by simply loosening the set screw, swinging the link downwardly, loosening the collar 27, withdrawing the barrel 26, whereupon the shaft may be withdrawn and a new disk applied thereto. Obviously the barrel is normally held against any possibility of movement and the set screw in its retracted position may not be lost, it being appreciated, as aforestated, that this set screw will also not shift in the pocket of the user, with the result of an untensioning of w the spring and failure of the lighter, necessitating a readjustment of the parts.

It is intended that numerous changes in structure might be resorted to without departing from the spirit of the invention, which is defined in the following claims.
